    Comments about Metra Replacement Speaker:

    great low cost replacement for a blown factory speaker. you have to cut the factory wires, but still a breeze to install.

    • Q:

      Are these 6" x 9"? My factory speakers have loose connections, so they turn on and off from time to time. Especially occurs during bumps in the road. My rear factory speakers are only 40ohm, and will these be able to replace those?

      It's a 1998 Pontiac Sunfire, and it has small strange brackets that plug into the speakers...each bracket has two colored wires connected to it.

        These speakers are like most aftermarket speakers and they do not have a specific connector. You will have to modify your vehicle harness to attach to the speakers. The dimensions are 2" H x 4" L x 6" W. It would be best to find out the wattage of your factory speakers instead of the resistance so you can get the optimal replacement speakers. These particular ones are rated at 12.5 watts.
